Summary: In u-boot 08r1.5 and trunk, when SCLK is high, it can't boot up in BF533-STAMP
In u-boot trunk, BF533-STAMP, set VCO_MULT to 45, CCLK_DIV to 1 and SCLK_DIV to 4, u-boot can't boot up.
It used to be ok in 08r1 with CCLK 497 MHz and SCLK 124 MHz.

did you update the sdram timings as well ? if not, you'll get random bit
failures because you arent refreshing sdram enough.

i talked to Robin ... the BF533-STAMP's cannot be run at SCLK greater than
100mhz as there is a large number of boards out there with a PCB defect in them
where you get memory failures at higher frequencies
